  • Page 3 (18-0037) CAUTION/REVISIONS When using the padded carrying case for the AM8a (P/N 87-0070C), DO NOT PLACE the power cord around the side of the AM8a in the manner demonstrated in Figure 1. Instead, be certain to WIND THE CORD UNDER THE CASING in the area between the feet, as shown in Figure Failure to follow this procedure could cause deterioration of the cord and increase the possibility of electric shock.

  • Page 48: Emulate Parameters

    The EMULATE parameters are used to define the values and timing of the events initiated by the AM8a. These parameters are only used when the Te/Line or Switch is set to CONFIG "MODE emulate". When set to "MODE monitor" they are not used, and also cannot be printed at a terminal.

  • Page 61: Dtmf Frequencies

    The A, B, C, and D digits are used for inter-office dialing and other special applications and may appear on some special-purpose dials (such as is used on the AM8a Program Keyboard and the example below). The frequencies can be determined from the figure below:...

  • Page 62: Mf(R1) Frequencies

    4.9.4 MF(R1) Frequencies: There are 15 frequency combinations that represent the possible MF (Multi-Frequency) tones that are used between Central Offices and some PBXs. For the AM8a to analyze digits as MF, a KP digit must immediately precede the first dialed digit.

  • Page 63: Tone On/Offms(Min)

    This GUARD (Tone ON time) time MUST be exceeded before the AM8a will analyze it. If the Event is shorter, it will be ignored. 4.11 THRESHOLD ANALYZE This menu controls the Tone Level and the Off Hook threshold that the AM8a will recognize. THRESHOLD: TONEdBm(min)

  • Page 64: Off Hkvdc(Min)

    Tip and Ring leads must fall below this threshold (towards zero, regardless of polarity) before the AM8a will recognize an OFF HOOK condition. This threshold will also affect the ability of the AM8a to detect dial PULSE digits. The next sub-section provides the procedure to determine the best setting of this parameter.
